The virtual battery is a power source that can simulate the charging and discharging characteristics of a battery pack under different operating conditions. Hence, the key step for a virtual battery pack to be able to replace the actual battery pack for the testing of a BMS is to establish an accurate model.
In this study, small-scale fault experiments that consider the inconsistency among cells, virtual connection fault, and external short circuits of the series-connected lithium-ion battery pack are carried out under laboratory conditions to verify the proposed method.
Hence, the key step for a virtual battery pack to be able to replace the actual battery pack for the testing of a BMS is to establish an accurate model. The current battery model mainly includes an electrochemical, black box, and the equivalent circuit models. The equivalent circuit model is commonly used for battery pack modeling.
Since the virtual battery pack can be quickly switched between different SOC states, temperatures, and aging states via the host computer, it can save a lot of time when using the virtual battery pack to conveniently evaluate the BMSs functions compared with that when using the actual one.

A series-connected virtual battery pack model through leveraging Copula’s method is formulated to capture the dynamics and inconsistency of individual batteries in the pack.
The developed lithium iron phosphate model features low computational efforts and is experimentally validated with different dynamical profiles, implying a high-precision virtual battery pack that is capable of reproducing the actual one.
